Topic Area 2B: Turbines for Oxy-Fuel Rankine Cycle Coal Based Power Systems: Topic Area 2B: Turbines for Oxy-Fuel Rankine CycleCoal Based Power SystemsApplications are solicited to produce advanced turbines for oxy-fuel basedpower systems. Successful applications will show a logical development ofturbine technology culminating with commercially ready machines in a 2015timeframe. It is anticipated that systems that utilize the subject turbinecouldachieve system efficiencies in the high 50s to high 60s range (depending onfuel: coal or natural gas) and require turbine working fluids in the 3000 ?3200 oF range. Turbines developed through this program should strive toenablelarge (300 ? 600 MW) advanced coal based power systems to achieve overallplantefficiencies in the 50 ? 60 % (HHV) range.Applicants are requested to propose a limited number of system studies toassess likely operating conditions for these machines. These system modelsshould be based on subsystems that are progressively advanced through timetoshow potential improvements in efficiency and cost of electricity.It is envisioned that the machines will incorporate high pressure,intermediatepressure and low pressure stages. These turbines are expected to operateonworking fluids comprised mostly of H2O and CO2 as a result of the directcombustion of oxygen and gaseous fossil fuels. Depending on the coal basedgasification process, gas stream cleanup and combustion process thepotentialexists for small amounts O2, and compounds of nitrogen, sulfur and tracecontaminants in the working fluid. Options for working fluid reheat shouldbeconsidered in the design. Developers should evaluate the effect of variousCO2/ H2O compositions on the aerodynamic blade designs. Final turbine exhaustshould be conducive to the separation and capture of CO2 in away thatpromoteshigh overall system efficiencies and minimizes the penalty of CO2compression.It is anticipated that the most challenging aspect of this turbinedevelopmenteffort will be rotating blade materials. Applications must discuss howtheseand other material issues will be addressed. Synergies between existingmaterial development efforts or existing technology should be leveraged.Forinstance it is envisioned that the low temperature condition (~1350 ? 1500oF)in the application of oxy-fuel turbine technology would be similar to thehightemperature condition in ultra supercritical steam turbines. Consequentlyit isdesirable to leverage possible synergies in materials developed for ultrasupercritical steam turbines (reference US DOE FE SolicitationDE-PS26-04NT42249-2B).Application Development and Project ImplementationApplications in Topic Area 2, Sub-topic B must include a phased approachshowing a logical organization of work and that allows for ?go? and ?no-go?decisions at the conclusion of each phase. The following phases arerequired:Phase I?Conceptual Design and R D Implementation Plan: Concept toCommercialDeployment; Phase II?Detailed Design and Validation Test Program; and PhaseIII? System Fabrication and Testing. It is expected that applications willhave more details regarding Phase I work. Since Phases II and III arecontingent on Phase I results specific details are not expected. HoweverPhases II and III must provide an anticipated scope, level of effort, andapproach. The R D Implementation Plan, a major deliverable of Phase I, willprovide the basis for negotiating and authorizing Phase II work andanticipating the magnitude of the Phase III effort. Offers are encouragedtoread the section of the solicitation titled ?General Guidance for PreparingtheResearch Development Implementation Plan?.Technologies that are developed beyond the conceptual phase may besubmitted asPhase II and Phase III applications. Technologies that are alreadydevelopedbeyond the detailed design phase may be submitted as Phase IIIapplications.It is anticipated that work subsequent to Phase III, such as full-scalepre-commercial testing, could be supported through other competitiveinitiatives.It is expected that in this Sub-topic Area Phase I efforts will be between1and 3 years, Phase II efforts will be between 2 and 4 years, and Phase IIIefforts will be between 2 and 4 years. These periods of performance areintended to be consistent with the goal of enabling a U.S. commercialofferingin a 2015 time frame.
